LOCOMOTlVE-VALVE.

SPECIFICATION forming part of Letters Patent No. 453,400, dated June 2, 1891.

Application filed November 25, 1890. Serial No. 372,618. (No model.)

To to whom it may concern:

Be it known that I, CHARLES R. KILLING- BECK, of the city of Troy, county of Rensselaer, and State of New York, have invented a new and useful Improvement in Locomotive Steam-Cylinder Valves, of which the following is a specification.

My invention relates to improvements in locomotive steam-cylinder valves to adapt them to supply exhaust-steam for heating purposes by constructing the exhaust-port of the valve so that a portion of the exhauststeam will pass to the smoke-stack in the usual way, and another portion of it will be directed into a pipe by which it is conducted to and through the cars, said pipe being preferably passed through one of the boiler-fines to the cab, whereat it is provided with a valve where the pressure and measure of steam to be utilized for heating purposes may be regulated.

Accompanying this specification to form a part of it there are two plates of drawings, containing four figures, illustrating my in vention, with the same designation of parts by letter reference used in all of them.

Of the illustrations, Figure 1 shows my invention as applied to a locomotive, with the pipe that conveys the exhauststeam (that is used for heating) through a boiler-flue to the cab, indicated by a dotted line. Fig. 2 is a cross-section taken centrally through one of the steam-cylinders of a locomotive, also through the steam-chest, through the valveseat and valve and a cross-partition arranged in that part of the exhaust-port which is in the slide-valve and a partition that is alsoarranged in that part of the exhaust-port which is in the valve-seat. This figure also illustrates in section the pipe which connects with the exhaust-port and conveys a part of the exhaust-steam to the smoke-stack and shows also the pipe which conveys away part of the exhaust-steam for heating purposes, with part of the latter pipe shown in section. Fig. 3 is a longitudinal central section taken through one of the steam-cylinders of a locomotive, the steam-chest upon said cylinder, the slide-valve, the valve-seat, with the piston and valve-rod shown in elevation. Fig. 4 is a perspective of the slide-valve of a locomotive steam-cylinder with what is its under side when in place, (shown as turned uppermost in the illustration,) and illustrating a partition arranged in that part of the exhaustport which is made in the under side of the slide-valve to divide such portion of the exhaust-port in two parts.

The several parts of the apparatus thus illustrated are designated by letter reference, and the function of the parts is described as follows: The letter C designates the steameylinder; S, the steam-chest; P, the steamcylinder piston; R, the piston-rod; B, the

boiler; S the smoke-stack; C the cab; T,

the tender, and E E the steam-ports.

The letter V designates the slide-valve, and 12 its operating-rod; A, that part of the exhaust port that is formed in the slidevalve.

The letters E E designate the steam-ports leading from the steam-chest to the steameylinder, over which ports the slide-valve V is reciproeatingly moved on the valve-seat V The letter W designates a partition that is arranged in that part of the exhaust-port A madein the under side of the slide-valve, and this partition is arranged to be parallel to the line of direction in which the slide-valve is operated by the rod o This partition WV divides that portion of the exhaust port formed in the under side of the slide-valve V, and indicated at A into two parts a and a The letter W designates a partition that is arranged within that part of the exhaust-port which is formed in the valve-seat V and indicated at A ,Fig. 2, and this partition W divides said exhaust-port part A in two inclosures b and b with said partition XV arranged to be verticallyin line with the partition part WV, formed in the slide-valve V, before described. As thus made and arranged the eXhaust-port is divided in two parts 13' B by the partitions NV and V so that as the slide-valve moves over the face of the valve-seat, these partitions being vertically in line, and that one of the latter arranged in the slide-valve being parallel to the movement of the latter, there is a constant division of the exhaust-steam, one portion passing from the part a of the exhaust-port of the slide-valve into the part b of the valve-seat, said two parts of the exhaust-port forming the chamber B, and the other part of the exhaust-steam passes through the exhaust-port part a of the slide-valve into the exhaust-port part 1) of the valve-seat, said two parts of the exhaust-port producing the chamber 13 The letters 1) designate a pipe'leading from the exhaust-port part B to the smoke-stack of the locomotive, and the letter 19 designates another pipe leading from the exhaustport part B to pass through one of the boilerfiues to the cab, and from thence by connection with the passenger coaches. (Not shown.)

The letter K designates a check-valve arranged on the pipe 19 and V a valve on the said pipe arranged within the cab.

Preferably the exhaust-port part B is made to take steam a little sooner than the exhaustport part B, and for this purpose the exhaust-port part a, formed in the under side of the s1ide-valve, is given a little lead, as shown at Z, Fig. 4, by beingmadealittle longer than that part of the exhaust-port indicated at B. The chamber B is preferably made smaller in area than the chamber B As thus made and arranged a part of the exhaust-steam is available for heating purposes, with the measure of itnecessary for that purpose regulated by the engineer in charge of the locomotive.

Vhile I have shown my invention as applied to a locomotive steam-cylinder to utilize a part of the exhaust-steam for heating purposes, my invention maybe applied to any steam-cylinderhaving an equivalent arrangement of steam -chest, sliding valve, valveseat, and exhaust-port for like uses.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

' 1. The combination, with a steam-cylinder having a piston and provided with a valveseat having steam-entry ports leading to said cylinder and an exl1aust-port leading therefrom, of a two-part partition dividing the exhaust-port in two parts, and a pipe connected with each of the divided-off exhaust-port parts to conduct steam therefrom, substantially in the manner as and for the purposes.

face and constructed with a valve-seat having entry-ports leading to the stcanrcylinder and an exhaust-port part leading therefrom, of a partition arranged in the exhaust-port part of the sliding valve, apartition arranged in the exhaust-port part of the valve-seat, said partition being in line with the partition in the slide-valve exhaust-port part, and a pipe connecting with each of the dividedoif parts of the exhaust-port, substantially in the manner as and forthe purposes set forth.

steam-cylinder that hasa piston and is provided with a sliding valve constructed with an exhaustport part formed in its under face and provided with a valve-seat having entry-ports connecting with said cylinder, and an exhaustport part which in connection with the exhaust-port part formed in the slide-valve conducts exhaust-steam from said cylinder, of a partition dividing the area of the exhaust-port part of the slide-valve in two parts, a partition arranged on the valveseat exhaust-port part to be in line with the partition in the slide-valve exhaust-port pipe, a pipe connecting with one of the divided-off areas of the exhaust-port, and a pipe connected with the other divided-off area of the exhaust-port and provided with a valve, substantially in the manner as and for the purposes set forth.

4. The combination, with a steam-cylinder having a piston and provided with a valve seat having steam-entry ports leading to said cylinder and an exhaust-port leading therefrom, of a two-part partition dividing said exhaust-port in two parts, with one of said exhaust-port parts constructed to take steam in advance of the other, and a pipe connecting with each of said exhaust-port parts to convey steam therefrom, substantially in the manner as and for the purposes set forth.

5. The combination, with a steam-cylinder having a piston and provided with a valveseat constructed with steam-entry ports leading to said cylinder, of an exhaust-port leading therefrom, with said exhaust-port divided in two parts, and a conduit-pipe leading from each of said divided exhaust-port parts, substantially in the manner as and for the purposes set forth.
